GREASE-PROOF PAPER VESSEL.

Specification of llettera Patent.

ori in l application filed ma as, 1912, Serial No. 699,097. invaded and this-application filed October 11, 1912. Serial 110. name.

To all whom it may concern Be it known that I, HERBERT L. G. Moons, a citizen of the United States, residing at Richmond Hill, in the county of Queens, State of New York, have invented an Improvement in Grease-Proof Paper Vessels, of which the following is a specification.

My invention relates to a sealed paper vessel for holding oils and greasy substances, and is a modification of the invention shown and described in my co-pending application Serial No. 699,097, filed May 23rd 1912, the present application being a division of said application. 1

The object of the present invention is to render the vessel proof against leakage of the most penetrating oil or greasy substance, an to accomplis original application, I provide a body with a bottom and cover, each part being formed of a piece of paper or other fibrous material covered on both sides with a grease proof material and connected together in 'such manner thatmll edges of the fibrous like reference characters indicate like parts throughout the several views, Figure 1 is a vertical section illustrative of a vessel constructed according to my invention, but showing the parts each in one thickness to economize space on the drawing. Fig. 2 is a sectional plan in enlarged size of a portion of the bod part taken at a point indicated by the broken line a: a: Fig. 1, and illustrating the preferred manner of protecting the edge of the inner lap. Fig. 3 is a similar view. to Fig. 2 illustrating a slightly modified form of covering the edge of the inner lap. Fig. 4 is asimilar view showing another slight modification in the manner of covering said edge. Fi 5 is a sectional view enlarged showing t e upper left hand portion of a vessel constructed according to m invention. Fig. 6 is a view similar to Fig. 5 of the lowe; right hand portion of a vessel constructed according to m invention. Fig. 7 is a plan view of a b ank for the grease proof covering and inner lining of my improved vessel. Fi 8 is a plan view of one form of the this, as in my center member of my improved vessel. Fig. 91s a similar view to Fig. 8 of another form of the filler or fibrous center member. Fi 10 1s a sectional view taken at approximate the line y 3 on Fig. 7 of the complete blank composed ofa. filler or fibrous center member and an inner and outer coverin of grease proof material both out to the orm shown in Figs. 7 and 8, and the respective edges of same. ent preliminary to forming the vessel. Fig. 11 is a view similar to Flg. 10 of a completed blank formed of an outer and inner grease proof covering of the form shown in Fig. 7 and a center fibrous filler cut to the form shown in Fig. 9 in which case the edges of the grease proof coverings only are bent over the edges of the center filler. Fig. 12 illustrates the manner in which the top and bottom of the body portion will be folded when the vessel is formed with the filler or fibrous center cut. of the shape shown in Fig. 8 and the edges bent as "shown in Fig. 10. Fig. 13 is a cross section of a portion-of the cover illustrating a. modified form of protecting the edge of the fibrous member.

1 indicates the body ortion of a vessel which is preferably cylindrical and which may be of uniform circumference or tapered. 2 indicates the bottom of the vessel, and 3 the cover of the same. Each of these parts are formed of a paper or other fibrous center member a covered on each side with grease proof material I) a. The grease proof material I; a is caused to adhere to the paper or fibrous member a by any suitable adhesive material.

In forming the body member, the grease proof coverin material b c is made of a eater lengt than the paper or other brous member a at that end which comes within the vessel whenthe body portion is folded upon itself, so that the extended ends "of such grease proof material may be turned over the cut edge of the paper or other fibrous center member a, as shown in Figs.

e e roo cover ma ma .0 may be extendgd on both si d s ofthe paper or other fibrous member a at one end so that it may be folded over the edge of the inner lap in the manner shown in Fig. 4, or it may be extended on only one side of the member a at one end so as to be folded over the edge of the inner lap in the manner shwn in Fig.

2 or that shown in. Fig. 3.

'the'ends, and fold over the op osite ed of one half ,of the blank towar 'each at er is illustrated in Fig. 12 wherein a thicknesses of the blank are folded-in the folds 5 and 6, but if desired the grease proof material b a may be extended beyond the neon one end as before described), longitudinally extended 'intot e -while at a and flat upon the blank, while theed es at the other side of the cuts 4.- are f'olde over in alike manner toward each other but upon the opposite side of the blank as shown m gr portions 5 and t the sides esive material. ortion three Fig. 10. These lapped over 6 are preferably secured a of the lank by suitable a This manner of forming the body member a (as well and these ortions' of the grease roof material fol ed over the cut edges 0 the member a, as illustrated in Figs. 5, 6 and 11.

It will be seen that whether the folds 5. and 6 are of the three thicknesses. of material as shown in Figs. 10 and 12, or whether such folds are of the grease proof material only, as shown in Figs. 5, 6 and 11, that, when'the body ortion is formed by rolling the blank desired shape for use, no fold either at the top or bottom of the vessel comes either on the inner or outer surface of the vessel, and that when the folds 5, 6, are of the ease proof material only, there will be no olded over edges of the center member longitudinal edges of the (1 either at the top orbottom of the vessel,

while at the same time all the cut edges of the center member a are covered by the folded over portions of the grease proof material b a.

Ata predetermined distance from the upper edge of the body portion, an annular groove *7 is formed in the inner surface, predetermined distance from the bottom edge of the body portion a similar groove 8, is formed.

The cover 3 is of a shape corresponding with the shape of the vessel at its upper part I and is of a size adapted to be forced into the .lfolded over upon itself as shown in 'but if desired the fibrous member a of the annular groove 7, so that it'will fit snugly therein.

In the preferred form ofcover, the edge is Fig. 5,

be cut of a size to snugly fit the cover .ma

y 7 in the body. portion, and

annular groove I the grease proof covering on the bottom' of the coverbe cut of a larger diameter, so that 'it may be folded over the edge of the fibrous member and thus protect such edge from contact with the contents'of the vessel, as

illustrated b either case t e folded over portion is caused the sectional view Fig. 13. in

to closelyadhereito the top surface of the cover by a suitable adhesive material. I

The bottom 2 has its edge folded over downwardly upon itself, which folded over port1on is caused to closely adhere to the under surface of the bottom ,by a suit-able adhesive material. This bottom is of a shapecorresponding with the shape of the lower art of the vessel, and is of a size adapte: to be forced into the annular oove 8.

. When the bottom 2 is forced into the groove 8, it fits therein suficiently tight to effectually seal the bottom, but as an addi-- tionalprecaution I prefer to dip the lower portion of the vessel in shellac or other suitable sealing substance. After the bottom has been thus positively sealed, the vessel is ready for fillmg, and having received its contents, the cover 3 is pressed into the annular groove 7, when the top of'the cover is sealed in a'similar manner to the bottom, and in addition to such sealing, the entire exterior of the vessel may, if desired, be

1 coated with the substance known as waterglass which gives a finished appearance to the same. I

It will readily be seen that in a vessel constructed as above described, the fibrous member a and all the cut edges of theseveral parts are positively protected from contact with the contents of the vessel, and the most penetrating substance cannot possibly leak or ooze through the vessel at any point.

I claim as m invention:

1. A vessel or holding oily substances, provided with a suitable cover and bottom and formed .from a-blank composed of a fibrous member coveredon both sides with a grease-proof material, said blank having a notch on each side midway between the ends, the opposite edges of one half of said blank being folded over toward each other upon one side of the blank, and the ed es on the other'half of said blank being olded over toward each other upon the opposite side of the blank whereby when the blank is rolled into shape there will be no fold on the inner or outer surface either at the. top or bottom of the vessel, the grease-proof material being extended beyond the edge of the fibrous member on the inner lap of the blank tudinal edges of the fibrous member, said extended portions of the ase-proof material having a notch on eac side of the fibrous member midway between its ends, the opposite extended portions of the grease-proof material on one half of said fibrous member I any fold on the inner or outer surface either being folded over toward each other upon one side of the fibrous member, and the other opposite portions of said extended 5 greaseproof material being folded over to- Ward each other upon the opposite side of the fibrous member whereby when the blank is rolled into shape there Will be no folded over edge of the fibrous material 1 either at the top or bottom of the vessel, nor

at the top or bottom of the vessel, the grease-.

proof material being extended beyond the edge of the fibrous member on the inner lap of the blank and folded over such edge.

Signed by me this 9th day of October 1912.
